Wireline Center Spear Feature

There are many sizes and models of steel wire external center spears, and different internal center spears can be selected according to different tubing sizes.

The wireline center spear is generally used when a traditional wire grab has been unsuccessful. The barbs, positioned around a centre mandrel allow for a more efficient penetration into a tight ball of wire, compared to the pronged arm style of a wire grab. As the Centre Spear is effectively non-releasable, it is generally run with a disconnect arrangement directly above it to provide a release feature if the parted wire cannot be retrieved back to surface.

Wireline Center Spear matters needing attention

Before using the outer Center Spear, the wire finder must first be lowered to form the wire nest in the well to facilitate the smooth fishing of the inner spear.
